I like that this version of unixware has both 32 bit and 64 bit versions. It was easy to install and configure. There are only minor differences between the two. The installation will take some time, but it's worth it. This product is very reliable. I have been using it for years without any problems. It's also a good choice if you need an enterprise level solution. I have used this in many different environments with great success. I highly recommend this product. We use this as our main operating system for our servers and desktop computers.
